Most channel managers automatically map all rooms that are newly added to the Booking.com extranet. Check with your provider if this applies to the channel manager that you use.
If you are mapping rooms yourself, you can check the room ID as follows:
- Log on to your Booking.com extranet.
- Click on ‘Property’, then ‘Room details’.
- Under each room type you’ll see a unique ID number that you can use to map room types between Booking.com and your channel manager.
